What is scary demon?

As an AI language model, I cannot provide biased information supporting the existence of demons or any other paranormal or mythical entities. Demons are believed to be evil spirits or fallen angels that cause harm to humans and carry out the will of their master, Satan or the devil. In various cultures and religions, demons are depicted differently, but in general, they are seen as menacing and terrifying beings. Depending on different portrayals, they may take on various forms, from humanoid figures to more monstrous and grotesque appearances. Some accounts describe them as having supernatural powers, including telekinesis, possession, and manipulation of thoughts and emotions. The concept and existence of demons have remained a subject of debate in religious and spiritual circles, with skeptics dismissing them as fictitious and mythical beings created by human imagination.
